EU EN 1515-2:2026 Takes Effect，Leakage Limits for Flanged Valves Tightened by 30%

On July 1，2026，the EU began implementing the new version of the industrial valve standard EN 1515-2:2026，which raises the sealing performance requirements under normal-temperature operating conditions for flanged valves with pressure ratings of PN16 and above，and adds low-temperature cycling test requirements。For valve manufacturing，export，certification，and delivery processes targeting the EU market，this is not merely an adjustment to the wording of the standard，but a practical change directly related to whether products such as control valves，globe valves，and gate valves can still complete compliant market entry under the new requirements。

The new requirements have been clearly implemented

According to the information provided，the EU officially implements EN 1515-2:2026 from July 1，2026。This revision targets flanged valves with pressure ratings of PN16 and above，reducing the maximum allowable leakage rate limit under normal-temperature operating conditions by 30%，while adding low-temperature cycling test requirements。

The confirmed direct impact is that control valves，globe valves，and gate valve products exported from China to the EU will face new compliance requirements。For models that have not passed the new version type test，it has been clearly stated that they cannot enter the EU market with the CE mark affixed。

The impact is not only on the manufacturing side；foreign trade and delivery chains are also under pressure

Export enterprises first face changes in market access thresholds

From an industry perspective，the reason direct trading enterprises are affected is the most straightforward，because the new version of the standard has already been linked to EU market access conditions。The impact is mainly reflected in model compliance confirmation，customer order acceptance judgment，export document preparation，and delivery feasibility assessment。What deserves more attention at present is that enterprises need to distinguish which models on sale have completed the new version type test，and which products still remain under the conditions of the old version of the standard。

Manufacturing processes need to re-examine testing and product boundaries

For processing and manufacturing enterprises，the impact is not only on finished products leaving the factory，but on whether the product verification route meets the new requirements。The tightening of the normal-temperature leakage rate limit by 30%，combined with the added low-temperature cycling test requirements，means that the type-test adaptability of relevant control valve，globe valve，and gate valve products will become a key link。From observation，enterprises need to focus on checking the affected pressure ratings，connection forms，and export applications，so as to avoid continuing to offer models that have not yet completed new-version verification to EU customers at the original pace。

Pressure on certification，documentation，and supply chain coordination will rise simultaneously

For supply chain service enterprises，participants related to certification services，and teams responsible for delivery coordination，the main impact appears in data consistency，test status confirmation，and delivery schedule management。Because models that have not passed the new version type test cannot be affixed with the CE mark，relevant documents，test conclusions，and customer communication content need to remain consistent。For orders in transit，stocking arrangements，and delivery commitments，more detailed verification will also need to be carried out subsequently around the requirements of the new version of the standard。

Which issues should be watched more closely in current practice

First confirm the affected models，rather than making a broad judgment on all products

From the analysis，enterprises first need to screen by product category and technical conditions，with the focus on control valves，globe valves，gate valves，and flanged products of PN16 and above。In practice，the area most prone to deviation is conflating an enterprise's overall qualifications with the compliance status of specific models，whereas the actual focus of the new requirements lies in whether specific products have passed the corresponding type test。

View changes in test requirements together with the market delivery schedule

The added low-temperature cycling test requirements mean that when enterprises arrange testing，certification，shipment，and customer confirmation，they cannot look only at the existing order schedule。What deserves more attention at present is that the effective date of the standard has already been clearly defined，and business departments，technical departments，and foreign trade teams need to make coordinated judgments around the same time node，so as to avoid situations where sales can accept orders but compliance documents have not yet been completed synchronously。

Customer communication should focus on verifiable information

For enterprises that have already established a presence in the EU market，the focus of customer communication should be whether the model is subject to the new requirements，whether the corresponding type test has been completed，and whether subsequent delivery documents are complete，rather than making a general statement that it “complies with EU standards”。From the perspective of actual business implementation，the closer it gets to shipment and customs declaration milestones，the more likely customers are to pay attention to test status and conditions for mark usage，so enterprises need to unify their internal information statements as early as possible。

Implementation details of the standard still need continuous verification

From observation，the known information is already sufficient to show that access requirements are tightening，but at the execution level，enterprises still need to continuously verify subsequent official wording，test applicability boundaries，and specific document requirements。Between the effective implementation of the standard and full business implementation，there is usually still work required to confirm terminology interpretation，the applicable scope of documents，and model correspondence，and this part cannot be judged solely based on information transmitted by the market。

This is more like a compliance tightening signal that has already been implemented

As observation and analysis，this information is more appropriately understood as a compliance change that has already entered the implementation stage，rather than a policy signal that still remains at the stage of soliciting opinions or discussing directions。Its clarity is reflected at three levels：the effective date has been given，the applicable categories and pressure ratings have been indicated，and the consequence that models failing to pass the new version type test will be unable to affix the CE mark has also been made clear。

At the same time，whether this change will trigger further adjustments in product design，testing arrangements，and customer procurement habits on a broader scale remains an industry dynamic that needs continued observation。At the current stage，the most practical impact is still concentrated in EU market access and export compliance processes，rather than being generalized as the entire operating outcome of the whole valve industry。

For EU business，the focus has shifted from understanding the news to checking implementation

Overall，the core signal released by the official entry into force of EN 1515-2:2026 is very clear：the EU is further tightening sealing performance and testing requirements for flanged valves，especially products of PN16 and above，and whether relevant models can complete the new version type test is now directly linked to their qualification to enter the EU market。For the industry，this information is more appropriately understood as a practical change that will affect order judgment and delivery arrangements in the short term，and also as a compliance trend signal worthy of continued tracking。

Basis of this article and directions for subsequent verification

This article is generated based on the information title，event occurrence time，and event summary provided by the user。The information used includes：the EU's newly revised EN 1515-2:2026 officially taking effect，the implementation date being July 1，2026，the leakage rate limit for flanged valves being tightened by 30%，the addition of low-temperature cycling test requirements，and the fact that relevant models that have not passed the new version type test will be unable to enter the EU market with the CE mark affixed。

For similar industry information，subsequent verification usually needs to continue in combination with official announcements，standards organization documents，enterprise announcements，industry association information，and reports from authoritative media。Because no specific official source links were provided in the input，this article does not cite corresponding specific links，and it remains necessary to continue paying attention to whether standard implementation rules，applicable boundaries，and relevant compliance statements are further clarified。
